Abstract

In urban environment trees play a significant role, provide affirmative impacts on urban microenvironment by transpiration, canopy and reflection actions hence support to decrease the effect of heat island. The quality of life in a metropolitan city is greatly influenced by urban microenvironment. Therefore, contemporary researchers have progressively focused their research study on urban microenvironment. This paper shows the micro environmental impact of Ficus virens and Conocarpus erectus plant species on Karachi's urban landscape and environment quality. A sequence of field measurement was conducted during pre-monsoon of 2023 to evaluate the impact of these species on their near environment by examining parameters such as light intensity reduction, wind velocity, air temperature and humidity. The result showed that Ficus virens decreased average maximum surface temperature reduction of 21.825°C and average maximum light intensity reduction of 110502 Lux, while Conocarpus erectus decreased 16.825°C and 88780 Lux. During study time average air temperature, humidity and wind velocity were 29.729oC, 69% and 1.23m/s respectively. The outcomes of this research work have important implications for urban planning and environmental conservation, providing essential information for decision-makers, landscape designers, and environmental supporters seeking to produce more sustainable and improved urban spaces in the face of prompt urbanization. This research work not merely enhances the academic address on urban ecology but also deals practical strategies for encouragement sustainable and resilient urban settings.
